LEAD-ACID BATTERY WITH SILICA-CONTAINING GEL ELECTROLYTE AND GLASS FIBRE MAT ELECTRODE SEPARATOR MATERIAL

摘要

This invention is directed to a lead-acid battery utilizing a novel electrolyte which includes a silica component. The silica component includes silica particles, means for repelling the particles from each other and for catalyzing the formation of siloxane cross-linkages and a sulfuric acid component. The lead-acid battery includes a container, a plurality of electrodes substantially enclosed by the container, and an electrolyte in substantial physical contact with the plurality of electrodes. A novel separator material having a silicate component for use in a lead-acid battery is also included in this invention. The separator material includes a silicate component integrally mixed with an oxygen compound of boron forming a microfiber mat. The mat has a pore size between about 0.5 to 10 microns in diameter and an electrical resistance of about 0.01 ohms per square inch for a 0.05 inch thickness.
